CROSS-REFERENCE TO RELATED APPLICATION

This is a continuation of co-pending U.S. patent application Ser. No. 16/531,033, which was filed on Aug. 3, 2019, the entire disclosure of which is incorporated herein in its entirety.

FIELD OF THE INVENTION

The present invention relates to beverage brewing and in particular to a brewing device for hot or cold brewing of beverages.

BACKGROUND OF THE INVENTION

Several types of beverages, such as coffee, tea, and herbal drinks, are brewed by infusing or steeping ground or shredded beverage material in water or other liquid. For quick brewing, hot water is typically used. However, cold brewing, that is, infusion of the beverage material in cold or room-temperature water rather than hot water, is sometimes preferred. For example, some coffee drinkers prefer the flavor provided by cold brewing, and bitterness can be avoided when brewing certain teas by steeping in unheated water rather than hot water. Such cold brewing is provided by submerging a portion of brewing material in unheated water for a period of time to allow the brewing material to infuse the water. While the steeping process may provide a desired result, the time required is longer than that required for brewing in hot water.

Conventional cold-brew steeps require a user to measure and pour a particular amount of brewing material into the steep. A pre-measured simple drop-in portion of brewing material would be convenient, particularly for use in a brewer that simplifies removal of the brewing material and clean-up of the brewer. A brewer that can be used for both hot- and cold-brewing would provide flexibility, and it would be advantageous if the brewer would be configured to speed the cold-brewing process. A further advantage would be provided by a brewer that could replicate the effect of a French press, by adding a compression feature to the brewing process. The ability to use either loose beverage brewing material or pre-packaged brewing material in a capsule or other container would make such a brewer would make such a brewer universally useful.

BRIEF SUMMARY OF THE INVENTION

The present invention addresses the above and other needs by providing a hot/cold beverage brewing device that reduces the time required to cold-brew coffee and other beverages. The brewer includes a container, and an elongated brewing material holder configured to be coupled to a lid of the container such that it is suspended from the lid.

DETAILED DESCRIPTION OF THE INVENTION

Various views of an exemplary beverage brewing device 10 according to the present invention are shown in FIGS. 1A, 1B, and 1C. The beverage brewing device 10 includes a container 12 for holding water during brewing, which has an open mouth for attachment of a container cap 50 of a cover 20. The container 12 can be made of any suitable material, such as plastic or glass, and can be transparent to allow viewing the beverage as it brews, although opaque or translucent materials can be used to form the container 12 as well. According to certain embodiments, a brewing material holder 30 is coupled to and suspended from an inside portion of the cover 20. As shown, the brewing material holder 30 is lined with a mesh material 30 a or includes mesh panels (see FIG. 7 ). A handle 18 is attached to the beverage brewing device 10, for example at the cover 20 as shown.

Referring to FIGS. 2 and 3A-3C, the container 12 includes closed sides or a closed sidewall, a closed bottom, and an open mouth, and can take any suitable shape, such as the generally cylindrical shape shown. The open top of the container 12 is configured to removably couple with the cover 20. For example, as shown, the rim of the mouth of the container can include threads 14 for mating with corresponding threads of the cover 20 for easy coupling. The container 12 and cover 20 can be otherwise configured for coupling such as by press-fit or snap-on couplers or any other configuration known to those skilled in the art.

A side view of the beverage brewing device 10 with the lid 15 removed is shown in FIG. 4 . A drive assembly 40 is housed under the lid 15 in the cover 20 and is configured to rotate the brewing material holder 30 during the brewing process. The drive assembly 40 shown is just one example of numerous drive assemblies that can be used as a drive element of the present invention. The drive assembly 40 can cause the brewing material holder 30 to rotate about a fixed axis, such as an axis parallel to the longitudinal axis of the brewing material holder to provide smooth rotation, or at an angle to the longitudinal axis so as to provide a more eccentric and therefore turbulent motion. The drive assembly 40 can also or otherwise be configured to provide a shaking or jittering motion to the brewing material holder 30. In summary, the drive assembly 40 is configured to provide any motion to the brewing material holder 30 that would cause advantageous agitation of brewing material held within the brewing material holder 30. The drive assembly can be powered by any known source, such as for example by direct current provided by batteries or a solar panel, alternating current provided via a plug configured to engage a wall socket, a spring-biased winding force, or by simple manual manipulation of a crank handle or other implement for turning the drive assembly 40. The lid 15 is removable for maintenance and repair of the drive assembly 40.

With reference to FIGS. 5A and 5B, the brewing material holder 30 includes a frame 39 to provide a base for mesh material. The frame 39 supports the brewing material while the mesh material allows water to pass through and around the brewing material in order to brew a beverage. The frame 39 also adds structural support for movement of the brewing material holder 30 by the drive assembly 40. For example, (see FIG. 6A) the frame 39 can include longitudinal members 32 and circular cross members 36, although any suitable structural configuration is contemplated for use as the frame 39. The frame can also include blades 34, in the sense of paddle blades, arranged on the interior portion of the frame 39, preferably within the mesh material, configured to urge brewing material within the brewing material holder to move with rotation of the brewing material holder 30. The frame 39 includes a bottom end 33 that can be integrally formed with the rest of the frame 39 or can be removably attached at the bottom of the frame 39, for example attached via a threaded interface. Fins 31 can be included on the outside of the bottom end 33 to encourage mixing of the liquid in the container 12 as brewing progresses. The bottom end 33 can be a solid bottom plate or can include mesh inserts, and in any case supports and contains the brewing material inside the brewing material holder 30. The brewing material holder 30 can include at least one holder handle 38 to facilitate lifting of the brewing material holder 30 from the container 12. The holder handle 38 can be fixed or, for example, pivotally attached at the top of the brewing material holder 30 by pivots.

The brewing material holder 30 can engage with the drive assembly 40 in any of a number of ways. For example, referring to FIGS. 6A, 6B, 6C, and 6D, triangular-ended teeth 37 can be disposed at the top of the brewing material holder 30, pointing outward from the brewing material holder 30 and configured to engage protruding bars 48 (see FIG. 8B) of the drive assembly 40 to couple the brewing material holder 30 to the drive assembly 40 such that rotation of the protruding bars 48 by the drive assembly 40 causes corresponding rotation of the brewing material holder 30, which in turn causes agitation of the brewing material in the water. This coupling arrangement is shown as an example only, and any coupling arrangement apparent to those of skill in the art can be used within the contemplated scope of the invention.

With reference to FIG. 7 , a mesh panel or sleeve 30 a is attached to the frame 39 of the brewing material holder 30 so as to cover open areas in the frame 39 to contain the brewing material 30 b within the brewing material holder 30. A single mesh sleeve 30 a as shown can be used, or individual mesh panels can be attached to the frame 39 to cover the open areas. The fabric of the mesh need only be fine enough to keep the beverage material contained within the brewing material holder, but should not be so fine as to overly restrict the flow of water through the beverage material during the brewing process. Examples of suitable mesh materials are fine nylon mesh, 75 micron opening nylon mesh, metal mesh material, and paper mesh material (for example, filter paper). Those skilled in the art will recognize that other mesh material may be used, and it is contemplated that a brewing material holder including such other mesh material could be used within the scope of the present invention.

So that the brewing material holder can be rotated or otherwise oscillated within the container 12 during the brewing process, the drive assembly 40 is configured to be coupled to the brewing material holder 30 and to the container cap 50, which in turn is configured to be coupled to the container 12. For example, with reference to FIGS. 8A and 8B, the drive assembly 40 can be disposed on top of the container cap 50. In this exemplary embodiment, lips 47 of the drive assembly 40 straddle a handle support 52 of the container cap 50 (see FIG. 9A) to seat the drive assembly 40 on the container cap 50 and fix the position of the drive assembly 40. Rotational motion can be provided by an electric motor 42 through reduction gears 44 and 46. The drive assembly 40 includes a drive coupler 45 rotationally coupling the gear 46 to the protruding bars 48 positioned to engage the triangular teeth 37 (see FIGS. 6A, 6B) of the brewing material holder 30 to functionally couple the brewing material holder 30 to the drive assembly 40. The brewing material holder 30 can be structurally coupled to the cover 20, such as to the cap 50 or directly to the drive mechanism 40, by any known mating structure, such as a press-fit coupling arrangement or a threaded outer sleeve. For example, a protruding ball 38 a at the top of the holder 30 can mate with a corresponding depression on the inner surface of the cap 50 to lock the holder 30 in place.

The reduction gears 44 and 46 have a ratio selected to provide the desired rotational speed of the brewing material holder 30 with respect to the rotational speed at the electric motor 42. Any suitable rotational speed or pattern of motion can be imparted by selection of the motor and gearing. For example, the rotational motion can be an oscillation of between 90 degrees and 270 degrees, at a cycle of between 30 cycles per minute and 90 cycles per minute, or it can be a continuous rotation in a single direction at any suitable rotational speed. The rotation can be made eccentric rather than smooth through the use of a cam or other non-circular gearing and the motor can be made to jitter the motion if desired. Further, the exemplary gearing is only one of many ways of translating the motor output to the drive coupler, and it is contemplated that any such mechanical translation can be substituted for the gearing arrangement within the scope of the invention.

With reference to FIGS. 9A, 9B, 9C, and 10 , the container cap 50 engages the container 12 during the brewing process. The brewing material holder 30 slides down through the container cap 50 into the container 12 and is supported by the container cap 50, for example, as shown by having an overhanging portion 55 at the top end of the brewing material holder 30 rest on a corresponding protruding lip 56 on the interior of the container cap 50. The coupler 43 engages the brewing material holder 30 when the drive assembly 40 is placed onto the container cap 50 to rotate the brewing material holder 30 during the brewing process. Thus, according to this arrangement, the holder 30 rotates freely on the lip 56 when the drive coupler 45 rotates. However, it is contemplated that any arrangement that allows for rotation of the holder 30 while it is supported by other elements of the beverage brewing device 10 is included within the scope of the invention. A spout 54 can be provided to facilitate pouring brewed drink from the beverage brewing device 10.

With reference to FIGS. 11A and 11B, a pouring lid 60 is provided that can replace the drive assembly 40 after brewing the brewed beverage. A lid handle 62 is provided that allows a user to remove the pouring lid 60. The pouring lid 60 can be rotated to align and separate a spout guard 66 from the spout 54 (see FIGS. 9A-9C).

An exemplary brewing material capsule 70 for use in the beverage brewing device 10 is shown schematically in FIG. 12 . The brewing material capsule 70 has an outer shell made of water-permeable material, for example, fine nylon mesh, 75 micron opening nylon mesh, metal mesh material, paper mesh material (for example, filter paper), and encloses and contains a quantity of brewing material 30 b measured for one or more servings of brewed beverage. The mesh sleeve 30 a described above for use with an exemplary embodiment is not required when using the capsule 70, so long as openings in the frame 39 of the holder 30 are not large enough to allow the capsule 70 to pass through the frame 39. The brewing material capsule 70 is preferably deformable, and when inserted into the brewing material holder 30, deforms to engage the blades 34 (see FIGS. 5A, 5B) inside of the brewing material holder 30, to cause the capsule 70 to rotate with the brewing material holder 30 to accelerate brewing. If not deformable, the capsule 70 can be inserted into the brewing material holder 30 with sufficient force to provide a friction fit between the capsule 70 and the blades 34 to cause the capsule 70 to rotate with the brewing material holder 30 to accelerate brewing. Thus, the brewing material holder 30 is configured such that a user can simply drop a conventional pre-packaged capsule 70 of beverage material into the brewing material holder 30 to brew the beverage. A brewing material holder 30 that includes the mesh sleeve 30 a provides flexibility in that loose beverage material or a beverage capsule 70 can be used advantageously with the beverage brewing device of the invention for hot beverage brewing or accelerated cold beverage brewing.

Although any conventional beverage capsule can be used advantageously with the beverage brewing device of the invention, particularly-shaped capsules can be provided for use with the device. For example, a polygonal blade-engaging capsule 70 a as shown in FIG. 13 a and a star-shaped blade-engaging capsule 70 b as shown in FIG. 13B are shaped to engage the blades 34 without deforming the capsule 70 a or 70 b or requiring a friction fit between the capsule 70 a or 70 b and the blades 34. The capsule may further include grooves in walls of the capsule angularly spaced apart to engage the blades 34.

Referring to FIGS. 14A, 14B, and 14C, a packaged brewing material capsule 72 for use in the beverage brewing device 10 can be enclosed in packaging for transport and storage that is preferably not water permeable, so as to prevent moisture from contacting the brewing material before brewing, and to retain coffee aromatics and particulate matter to preserve flavor. Preferably, the packaged brewing material capsule 72 includes a tear-away wall strip 74 to facilitate removal of the packaging. According to certain embodiments, the packaging top 76 and bottom 78 can remain when the tear-away strip 74 is removed, allowing water to flow through the sidewalls of the capsule 72. The packaging is preferably removed before the capsule is disposed within the brewing material holder 30 for brewing.

With reference to FIGS. 15A-15D, an alternative packaged brewing material capsule 74 for use in the beverage brewing device 10 includes a top tear-away wall strip 80, which can be removed as shown in FIG. 15B to facilitate removal of a wall 82 of the packaging. According to certain embodiments, the packaging bottom 78 can remain when the tear-away strip 80 and wall 82 are removed.

FIG. 16A shows another packaged brewing material capsule 84 for use in the beverage brewing device 10 and FIG. 16B shows this packaged brewing material capsule 84 with the brewing material in the water-permeable package 88 separated from the packaging material 86. After separating, the brewing material in the water-permeable package 88 can be inserted into the beverage brewing device 10 for brewing.

FIG. 16C shows the brewing material in a water-permeable package pressed out of an open bottom protective package 84 a after removing a bottom cover of the open bottom protective package 84 a. The bottom is configured to break away from the walls, and to be pressed against the brewing material in the water-permeable package 88 to press the brewing material in a water-permeable package 88 out of the protective package 84 a.

FIG. 17 shows an exemplary embodiment of a beverage brewing device 10 a pressing the brewing material in the water-permeable package down and out of the open bottom protective package. The beverage brewing device 10 a includes stops 92 in a brewing material holder 30′ and a drive assembly 40 a includes a ramming projection 94 that pushes the brewing material in the water-permeable package 88 out of the protective packaging and into the brewing material holder 30′ to be rotated or oscillated by the drive assembly 40 b to make a brewed beverage. The effect is similar to that of a French press brewer in which water is forced through compressed, coarsely-ground brewing material.

FIG. 18 shows a side view of an exemplary embodiment of a brewing device 10 b having a brewing material capsule 80 carried by a drive assembly 40 a. The brewing material capsule 80, after packaging material is removed from walls of the brewing material capsule 80, is inserted into a cage 82 and rotated or oscillated by the drive assembly 40 b to make a brewed beverage.

With reference to FIG. 19A, according to another aspect of the invention, a brewing material capsule 90 is provided that is configured to couple to and engage with the drive assembly directly, obviating the need for a brewing material holder 30. For example, the capsule 90, which is prepackaged to contain a measured amount of brewing material within a water-permeable package 91, can be configured with triangular-ended teeth 97 disposed at the top of the capsule 90, pointing outward from the capsule 90 and configured to engage the protruding bars 48 (see FIG. 8B) of the drive assembly 40 to couple the capsule 90 to the drive assembly 40 such that rotation of the protruding bars 48 by the drive assembly 40 causes corresponding rotation of the capsule 90, which in turn causes agitation of the brewing material in the water. This coupling arrangement is shown as an example only, and any coupling arrangement apparent to those of skill in the art can be used within the contemplated scope of the invention.

With reference to FIG. 19B, the container cap 50 engages the container 12 during the brewing process. The capsule 90 slides down through the container cap 50 into the container 12 and is supported by the container cap 50, for example, as shown by having an overhanging portion 95 at the top end of the capsule 90 rest on a corresponding protruding lip 56 on the interior of the container cap 50. The coupler 43 engages the capsule 90 when the drive assembly 40 is placed onto the container cap 50 to rotate the capsule 90 during the brewing process. Thus, according to this arrangement, the capsule 90 rotates freely on the lip 56 when the drive coupler 45 rotates. The capsule 90 can be otherwise structurally coupled to the cover 20, such as to the cap 50 or directly to the drive mechanism 40, by any known mating structure, such as a press-fit coupling arrangement, a friction-fit arrangement, a snap-fit mating arrangement, or a threaded outer sleeve. For example, a protruding ball 98 at the top of the capsule 90 can mate with a corresponding depression on the inner surface of the cap 50 to lock the capsule 90 in place. In any case, the capsule 90 couples with and is suspended from the cover 20 of the brewing device 10 without the need for a brewing material holder, simplifying the brewing process. The capsule 90 is also rotationally coupled to the drive assembly 40 so that it can be rotated to expedite the brewing process.

Thus, the brewing device of the present invention can be used for both hot- and cold-brewing, and is configured to speed the cold-brewing process. The brewer has the ability to use either loose beverage brewing material or a simple drop-in portion of pre-packaged brewing material provided in a capsule or other container. Particular embodiments of the brewer replicate the effect of a French press, by adding a compression feature to the brewing process. Use of the brewer of the invention is flexible and convenient, and simplifies removal of the brewing material and clean-up of the brewer.
